Satellite intensities in the K-shell photoionization of CO.

A recently proposed scheme for calculating E-shell ionization cross sections in atoms and molecules using the relaxed-core Hartree-Pock (RCHF) approximation is extended to the treatment of shakeup processes. As an example, this scheme is applied to the m-~* satellites in the C ls photoelectron spectrum of CO. These results for the (SO, S1) pair of ~-~* satellite states reveal strong interference effects between the "direct" (bound-free dipole integral) and "conjugate" (bound-free overlap integral) contributions in the transition moment at near-threshold energies. These effects are particularly dominant in the kyar subchannel and, for the triplet-coupled satellite (S1), lead to a drastically increasing cross section
